The way your question is worded, the probability is zero. One ace is not two aces.

Answer:

$\large\boxed{7.\ B.\ 8s^2+16s+1}\\\\\boxed{8.\ D.\ -15t^9u^{11}}\\\\\boxed{11.\ C.\ 3,\ -2}$

Step-by-step explanation:

$7.\\(3s^2+7s+2)+(5s^2+9s-1)=3s^2+7s+2+5s^2+9s-1\\\\\text{combine like terms}\\\\=(3s^2+5s^2)+(7s+9s)+(2-1)\\\\=8s^2+16s+1$

$8.\\(-3t^2u^3)(5t^7u^8)=(-3\cdot5)(t^2t^7)(u^3u^8)\qquad\text{use}\ a^na^m=a^{n+m}\\\\=-15t^{2+7}u^{3+8}=-15t^9u^{11}$

$11.\\n-the\ number\\\\n^2=n+6\qquad\text{subtract}\ n\ \text{and}\ 6\ \text{from both sides}\\\\n^2-n-6=0\\\\n^2+2n-3n-6=0\\\\n(n+2)-3(n+2)=0\\\\(n+2)(n-3)=0\iff n+2=0\ \vee\ n-3=0\\\\n+2=0\qquad\text{subtract 2 from both sides}\\n=-2\\\\n-3=0\qquad\text{add 3 to both sides}\\n=3$

1. the number 0 (for the real numbers) distributive property 2. a(b + c) = ab + ac or a(b - c) = ab - ac literal equation 3. an

Semenov [28]

the number 0 — additive identity
a(b+c) = ab+ac — the distributive property
an equation containing more than one variable — literal equation
the number 1 — multiplicative identity
the reciprocal of a number — multiplicative inverse

If x ≠ 0, then 1/x is its multiplicative inverse — true.

The product of a number and its multiplicative inverse is 1 — true.

A store sells 1/4 pound of beef for $0.75. If u are having a party and need 6 pounds of beef for hamburgers,using the unit rate,

hodyreva [135]

1/4 pound beef, b = $0.75

=》 6 pounds beef = (6)/ (1/4) × b

=》 6 pounds beef = 24 × $0.75 =$18.00
